WITNESS 4 TTORNEY portions so that if a failure occurs it may be corrected early in the progress of the failing clips along the ways; but they may be placed elsewhere in the ways, and there may be more than one for each rail. All the clips of course followthe bends 2 in the ways and all are subject to the action of the controlling means 12 whether or not they fail to receiveand hold the fabric A. If they do not fail, the fabric edge remains therein, while the jaws 7 of the clips are withdrawn from their jaws 6, and so release the fabric, until the peaks of the bends are passed, whereupon the jaws 7 return into the gripping relation. It any clip fails, the movement of the defective clip toward the opposite way as it passes around the bend 2 forces it against the stretched edge portion of the fabric (its j aw7 being already opened by the means 12), which thus enters the clip, ready Vto be gripped by said jaw as soon as the same is released by the means 12.

The means 12 functions with respect to eachclip jaw ,7 substantially the same as each wheel 10-41, though it is in the example a fixed cam; that is to say, as the clip takes the bend 2 in the way the extension 7 of its jaw 7 encounters the cam and the lW' is withdrawn, falling by gravity to gripping position assoon as the cam is passed.

Cam 12 is here provided with a fixed vertical bolt 13 which passes through a slot 14 inthe rail arranged transversely of way 2, the bolt having a flattened key 13 in the slot which prevents the cam from turning; the bolt has a clamping nut 15. V

hen the leading end of the goods is introduced into the machine, if the cams 12 remained at that time active to open the elips,the goods would fail to be caught and carried along. Henceat this time the bolts 13 are released and the cams shifted to the position lengthwise of slots 14 where they will fail to be engaged by the jaw extensions 7*, whereby the leading end of the goods will remain held by the clips until it has passed the bends 2, upon which the cams are returned to their normal or illustrated positions. i 1

Usually, both ways will be provided with the bends 2 and means 12, though this is not indispensable. j

Having thus fully described my invention, what I claim is:

1. A tentering machine comprising two sideby-side elongated structures having longitudinal spaced ways, tentering clips arranged to be guided bysaid ways and eachfadapted to undergo closing movement on each approach thereof to the corresponding way so as to hold the fabric'while travelling along such way and to undergo fabric-releasing movement on each departure thereof from said way, means to control such movements of the clips, one of said ways having, between the points at which said closing and releasing movements of the clips occur, a bend reaching toward the other way, and the clips guided by such ways being each adapted also to undergo fabric-releasing and closing movement at said bend, and meansto control the latter releasing andcl0siug movements of such clips.

2. A tentering machine comprising two side-by-side elongated structures having longitudinal spaced ways, tentering clips arranged to be guided by said ways and each adapted to undergo closing movement on each approach thereof to the corresponding way so as to hold the fabricwhile travelling along such way and to undergo fabric-releasing movement on each departure thereof from said way, means to control such movements ofthe clips, one of said ways having, between the points at which said closing and releasing movements of the clips occur, a bend reaching toward the other Way, and the clips guided by such way being each adapted also to undergo fabric-releasing and closing movement at said bend, and means to control the latter releasing and closing movements of such clips shiftable transversely of the ways.

In testimony whereof I aflixmy signature.
